Can a 2JZ make 750 rwhp on a completely stock bottom end, stock injectors, stock fuel pump, stock drivetrain and a blower swap with 30psi of boost? And this motor is still young. It is bound to go even higher.

The 99-01 GT 4.6 Modular blocks can take up to 1000HP with supports and a good crank, rod, piston configuration. Before I bought the Max when I was trying to sell my truck, I was going to buy my mom's 99 GT and slap a turbo kit from Turbolocity on it. They have dyno graphs of their test 99 GT 5-spd, completely stock bottom end, changed the fuel pump, MAF, infectors, and other things that come along with the kit, and at 10 psi w/ intercooler, puts 434RWHP and 547TQ to the ground, stock bottom end and tranny only thing needed is their complete kit. That is on their most radical program of the 3 on their custom chip, they recommend to run program 1 or 2, which makes right over 400 to the wheels. Take a look here, they just posted up some pics of this race 4.6 engine they are building, using the stock GT block, planning on making around that 1000HP mark with it too and it's going into a 2001 Saleen S-281 body.
And these guys with just the kit, nothing extra, say they still get 20-25mpg when not driving like they stole it
Still kinda wish I'd done that instead of the Maxima, but I'm only 20 years old so I have plenty of time to build a fast car!

Great thread!
This is a very interesting discussion guys...keep them coming. My question is, if the 2002 Max has hybrid engines (2.5), the 2004 Max has full 3rd generation, does that leave 2000-2001 Maxes to have 2nd generation and 1995-1999 Maxes to have the 1st gen?
From what I know, 2000-2001 engines has the VI which is not available from 1995-1999 Maxes (but....now we have MEVI).

Gen4.0 VQ30DE = 1st Gen VQ
Gen5.0 VQ30DE-K = 2nd Gen VQ
Gen5.1 VQ35DE = 2nd/3rd Gen VQ Hybrid is what it looks like.
Gen6.0 VQ35DE = 3rd Gen VQ: 280hp/270tq??
Somebody PLEASE go DYNO this puppy!
The 14.6 @ 95 that ga2000 was able to get is VERY impressive for a 3500 lb car with huge 18" rims, especially FWD. I think Nissan rated conservatively this time around and that the Maxima has a lot more than the rated 265hp/255tq. But somebody needs to dyno so we can find out!

V-6 engines do not have any first-order balance issues at 90-degree and 60-degree V-angles. A 60-degree engine is much preferred though because it's much narrower than a 90-degree. The mainstream Honda, Toyota, and Nissan V-6's are all 60-degrees.
The GM 3.8L is a 90-degree and that won't fit in a lot of their cars - only the larger ones. The VW/Audi 2.8/3.0L is also a 90-degree. The VR6 is a narrow angle 15-degree engine with a shared head. As far as balancing issues, it behaves more like an Inline-6 (naturally balanced) than a V-6.

I've already got a K&N cone filter on the MAF, but I can carry the stock box with me and hook it up to see the before and after gains. I'm definitely willing to have mine done to see what the actual numbers are though.
Let me know if anyone in the North FL area is willing to help out with this project, or knows anybody here that could help

AOD Tranny (more consistent)
Live Axle (switched from IRS)
Kenne Bell Blowzilla S/C unit at 24 PSi (massively more efficient than the stock Eaton)
Stock fuel pump with Kenne Bell Boost-A-Pump and IIRC stock injectors
Stock 32V heads (never had the valve covers off)
It's in this month's MM&FF Magazine. The car is just bada$$. And the scary part is, he really doesn't have "that" much money in the car overall (not comparitive to some of the other serious Mustang modders out there...)

There's the KB link for their setup. The guy who owns the '03 Cobra also has some kind of N2O system, but I do not recall what the exact setup is. I just loaned my magazine out, too...
Anyway, it is an absolutely awesome car for the money.
EDIT-- Another link on the car...

I still think that the 700-800 rwhp Toyota 3.0L 2JZ-GTE engines are the most impressive. 800+ rwhp from any car is impressive, but the Toyota guys are doing it on only 3.0L, not 4.6. And the 2JZ's I know hold together pretty well, even at very high boost. I have heard the guys saying at Corral.net that it is sorta hit and miss when boosting the 4.6L SOHC engine and that you ought to rebuild the internals first. That's even at low boost too (6-8 psi). I'm not sure if the DOHC motor is any different, though....

Everything is forged, everything set up for really high boost levels, low CR pistons, super strong forged internals all matched weighted ...it's got some massive potential. It'll easily do 2 BAR...

Ford HAD to do an outstanding job on the new Cobra since they focked owners a few years ago with the overated Cobra. The new one is damn near putting TO THE WHEELS what is stated in the brochure 390hp.
